Clio 172 - slow progress project

The lower AFR value should be better in theory as you are running richer at 12.1 than at 12.5. So you should get more power with the KTR box on.
After some talks with Chris from efi and some google searches, the best performance is at 12.8 to 13.5, but is a little risky to be in that range. Best safe output power is at 12.4 to 12.5. Running richer by only using another intake doesn't mean less air on the same injector duty cycle?

That's true and it may point to the fact that even changing the airbox may mean you'd benefit from a remap. Both figures seem a little low but that may be down to calibration. The difference between the two figures is what's interesting.

I don't have acces to a dyno run, as it was mapped remote. I could only see the afr from my car and the differences. In theory the ktec should run leaner. I bought and ph1 airbox, I will also test it.

My (best) solution for fitting ph1 airbox using silicone hoses. I have a bigger tb so stock ph1 hose does not fit on it. In this case I was forced to use a 70mm ID silicon elbow. Using just one the airbox fits very tight and I did not like that. Start searching the forums, but no solutions to fit it like on a ph1.
For this I use a 90deg hose and 45deg one and paaaatience.
...two hours later...

Some great updates on here mate. I somehow have managed to miss a load of your updates. Its brilliant you have a go at doing pretty much everything yourself. Car has really come along and looks great! I know it's not easy for you to get parts out there too.

I am not normally a fan of 182 replica exhausts, but really like that. How did you find the spoiler to fit? All looks very smart 👍

Hi there!
Thanks a lot for appreciation. I could not find anyone that could help so I start to work alone and I am very happy. It was not that easy to work alone on the engine, but I managed to get it done without any left screws :))
The spoiler is the one from Italy, with 2 lines on it instead of 1 like original Trophy. In order to fit it right, you need to enlarge the holes from edges (two on each side) to 10mm, or using a dremel tool to be more precise. Them some small M6 screws and thats all. It does fit fine if you enlarge the holes, impossible otherwise.
Now I am waiting for a Clio 200 Renault Sport badge to fit it on the left side:).
Cheers

Nice one. Sounds very similar to my replica spoiler. I also enlarged the holes on mine and fits well. I much prefer the brake light and style of the trophy spoiler.

Hi,

This year I will start working on a new engine on my Clio. A complet 197 head with a mod to fit 172 engine block, forged internals, 197 crank and...a turbo:)
For start I will run an ED turbo at 12 psi to see how it will be.

I will update soon with parts and other work.

Ph1 fuel rail does not fit 197 inlet, shame I did not figure it out before buying one.
So need to make the 197 fuel rail to accept return.
